WebHenry Gwyn Jeffreys Moseley (; 23 November 1887 – 10 August 1915) was an English physicist, whose contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. This stemmed from his development of Moseley's law in X-ray spectra. WebHenry Moseley was an outstandingly skilled experimental physicist. In 1913 he used self-built equipment to prove that every element's identity is uniquely determined by the number of protons it has. His discovery …

WebThe modern periodic table is based on Moseley's Periodic Law (atomic numbers). Moseley determined the number of positive charges in the nucleus by measuring the wavelength of X–rays given off by certain metals in 1913. The wavelengths of the X–ray emissions of the elements coincided with the ordering of the elements by atomic number. WebMoseley's law is an empirical law concerning the characteristic x-rays that are emitted by atoms. The law was discovered and published by the English physicist Henry Moseley in 1913. It is historically important in quantitatively justifying the conception of the nuclear model of the atom, with all, or nearly all, positive charges of the atom ...
